Description of App
WARNING: Only works on iPhone 6, iPhone 6 Plus, and iPad Air 2
ACCURATE BAROMETRIC SENSOR
This app displays the current pressure as detected by the barometer sensor inside iPhone 6 and iPhone 6 Plus. This means no network connection is required. You can get the current pressure anywhere your iPhone 6 or 6 Plus can go!
A CORNUCOPIA OF UNITS
Measure air pressure in a number of different units: inches mercury (inHg), kilopascals (kPa), torr (millimeters of mercury), atmospheres, millibar (mbar), or pounds per square inch (PSI). Measure altitude change in meters or feet.
SEA-LEVEL AIR PRESSURE ADJUSTMENT
Use your GPS-determined altitude to estimate air pressure at sea level to compare with weather stations around the world! (Note: this does not require cellular or Wi-Fi service)
APPROXIMATE ELEVATION CHANGE
Using changes in pressure, the app displays an approximate elevation change from a reset point that you control.

Device(s) App Was Tested On
This app is very accessible and simple to use. There is a switch button below the controls for selecting units of measurement. This switch button is for changing between actual and adjusted air pressure, and is off by default. When the switch button is toggled on, the app will "Use your GPS-determined altitude to estimate air pressure at sea level."
The APPROXIMATE ELEVATION CHANGE tends to be fairly accurate. Using this feature, a measurement from floor to ceiling within a room was accurate within a few inches.
